[AA][JumpThreading] Don't use DomTree for AA in JumpThreading (#79294) 
JumpThreading may perform AA queries while the dominator tree is not up
to date, which may result in miscompilations.

Fix this by adding a new AAQI option to disable the use of the dominator
tree in BasicAA.

Fixes https://github.com/llvm/llvm-project/issues/79175.
